In Congress, members belong to one of three main groups:
1. Democrats - This is one of the two main political parties. Most members who lean toward liberal or progressive ideas are Democrats.
2. Republicans - This is the other major political party. Members who lean toward conservative ideas are usually Republicans.
3. Independents - A small number of members identify as independents, meaning they are not formally part of either the Democratic or Republican party. However, they often work with one of the two main parties.
Most members of Congress are either Democrats or Republicans, with a few independents who often align with one of those groups on key issues.
